On-Premises Servers Products are Here! Introducing the Applications and On-Premises Servers Bug Bounty Program

Microsoft is excited to announce the addition of Exchange on-premises, SharePoint on-premises, and Skype for Business on-premises to the Applications and On-Premises Servers Bounty Program

That’s not all! The bounty also includes high-impact scenarios offering the highest awards to research in areas with the highest potential impact to customer security.
